I just added an air intake, exhaust, downpipe, etc to my 03-05 Dodge SRT-4, Caliber SRT-4 do I need to get a tune?

This is a common question for us at

Customers with 2003/2004/2005 Dodge SRT-4’s will add an air intake, downpipe, exhaust, turn up the boost with a boost controller, or other minor mod and think they have to tune for each mod.

Whenever customers think they need a tune for each mod, it means one of two things for us: 1) These are new owners that have never modified a car before and are just being precautious 2) These customers previously owned a Subaru, Toyota, Chevrolet, Ford, etc car that uses a mass air flow sensor.

All cars use either a Mass air flow sensor or a speed density map pressure sensor type sensor to determine how much air is flowing into the motor. In the photo below you can see a mass air flow sensor on a 2008-10 Chevrolet Cobalt SS Turbo.

For cars with mass air flow sensors, they cannot accurately adjust for changes made, and so generally they will require a new computer tune for each mod done (intake, exhaust, downpipe, intercooler, etc).

For cars with map sensors like just about every Chrysler made, they will automatically adjust for each mod you do and for the most part dont need a tune unless you do a major mod like change injectors or change the turbo.

Using higher wattage headlight bulbs in your car..

So you want to increase the light output of your headlights to light up the road better.

One way you can do that, is by adding a set of driving lights, or fog lights.

Another thing you can do, is change the headlights, or headlight bulbs. For todays discussion, we are going to talk about changing headlight bulbs.

Now, most OEM headlight bulbs are like 50 watts. You can generally change headlight bulbs by about 20% with no problems, but 30% and higher and you could have melted plugs, and or a fire hazard.

If you have already installed a set of higher wattage headlight bulbs and are having issues with flickering lights, or lights sometimes not coming on, its most likely due to a melted headlight plug.

Luckily, sometimes the dealership will offer replacement headlight pigtails, and sometimes you can buy them in the aftermarket by searching for your headlight bulb type and “headlight pigtail”.

So, morale of our story, is be careful with higher wattage bulbs than OEM bulbs in your car.

Check out the difference between a US spec fuel pump and Mexican spec fuel pump on a 00-05 Neon!

So a good friend of ours is doing some work on a Mexican spec, export Neon that is in the United States.
The owner is visiting for a few weeks and his fuel pump died after nearly 300 Kilometers, or nearly 200,000 miles of driving in Mexico.

So the fuel pump canister was removed and check this out.
This is a US spec fuel pump canister assembly. Look at the fuel filter sock on the end. Notice its a thin wafer, with plastic mesh.

This is the Mexican spec fuel pump canister assembly. Notice how the canister is the same, but the fuel filter end is more like a large can. This is to better filter out impurities in the fuel.

This is not the only difference between Mexican spec and US spec built Neons. We know the Mexican built Neons do not have airbags as Mexican Federal law does not require airbags in passenger vehicles, nor does Mexican Federal law require catalytic convertors, as well.

How to find a dynamometer close to you to dyno test your cars horsepower and torque.

Ok, so you have done some mods to your car and you want to find out how much horsepower/torque your car has.
You’ll need to find a dynamometer to test your car. If you dont know of any near you, its best to use the Dynojet search tool to find one in your area:

Now there are several brands of dynamometers, and the most popular one out there is the Dynojet Dyno.

Copy and paste this into a browser to find a Dynojet dyno.

The second most popular type of vehicle dynamometer is the Mustang dyno which works well but is not nearly as accurate as the Dynojet in our opinion.

Brushed steel finish car wraps. Check out the way this looks!

We came across a Mercedes van that was wrapped in a flat, no gloss brushed steel type finish. It also had a roof that had a flat, no gloss black brushed steel finish. Check it out. This is pretty interesting, you normally dont see a brushed steel finish like this, its almost always a car with a flat finish, or some wild color.

Anyways! Onto the pics!

Under the hood you can see the original color inside the engine bay, and the wrap on the fender that ends just inside the fender area.

Alex’s barn find 98 Neon R/T is up and running. Check out the before and after photos!

Our friend Sgt Alex Lopez bought this 1998 in 2012. When Alex found it, there was no engine, and most of the interior was missing.

It sat for a while, and Alex slowly built it up, and got it running again.

2012 vs 2017 photo:

Want to check out more photos from before Alex bought it? Check the link below.

When you think your wastegate actuator is bad, or failing, it 99.9% is probably not.

“I need a new wastegate actuator, my cars not getting positive boost pressure!”

Thats a statement when we hear, we know is 100% wrong. Way too often we hear that statement, and people think their wastegate is not working correctly and so they need a new one.

To explain why, lets go into detail on the way the wastegate actuator works.


Ok, so here is a Neon SRT4 turbofold with the top heat shield missing. We have a yellow arrow pointing to the wastegate actuator, and a red rod pointing to the wastegate flap.


So lets do a run down of the operation of the wastegate with an example of you driving in second gear as boost builds up when you stomp the gas.

– 15 psi of vacuum the wastegate is closed, and pulling on the wastegate flap to keep it closed.

Yyour now at 0 psi, the wastegate is still closed, and pulling on the wastegate flap to keep it closed. Boost is building fast.

5 psi. The wastegate is starting to open the wastegate flap, allowing some exhaust to bypass the turbocharger.

10 psi, boost is still building and the wastegate actuator is pushing the wastegate flap open more.

12-13 psi has been reached, and the wastegate flap will be opening and closing now to regulate boost pressure to the desired 12-13 psi.

So, because the wastegate regulates boost pressure, and its always pulling on the flap, if for some reason it failed, the boost pressure would be very high as it will not be regulating the peak pressure. You would never have zero psi or less with a failed wastegate actuator, you’d have 5-10, 20 psi OVER what it should be. 






Weight reduction and rotating mass – reduce your cars weight for more fun!

You want to have fun in your car, and have some enjoyment in the twisties and corners.

People are very often concerned about making more horsepower, having a better sound system, etc and one area thats frequently overlooked is the weight of the car, and more specifically rotating mass weight.

Now, any car can benefit from a weight reduction, but how extreme you want to take it depends on you.

Take for example our 2014 Dodge Dart GT.

One of the things we did to change our cars look, was to get a set of 18 inch Enkei PF01 wheels. These replaced the factory Dart GT wheels that looked like this.

Now, we dont have exact weights available at time of making this article, but the factory GT wheels were very heavy, and weighed something like 24/25 lbs each. The Enkei wheels we put on that you can see below weighed in at 18/19 lbs. Thats a savings of about 6 lbs on each corner.  That may not sound like much, but a 24lb weight savings on wheels is massive.

Now, with these new wheels, we noticed a difference in acceleration off the bat, the car handled better, it revved up much faster, and felt faster overall. This is because, in general anything that is rotating mass – ie, wheels, tires, brakes, axles, rotors, engine internals directly affects the engines performance.

Now, we also did some other work to our Dart to reduce weight.

Brakes – we used a custom made brake kit to reduce 16 lbs of rotating mass.

Pulley -we installed a lightweight crank pulley to reduce 3 lbs of rotating mass.

Seats – we pulled out the leather seats and installed cloth seats to save nearly 30lbs of weight. Most of the weight savings were from going from full power seats to manual seats, no heavy motors attached to the cloth seats!

So, we have reduced nearly 50lbs of rotating mass, and about 30 lbs of fixed mass. This is pretty incredible and its a difference you can feel when driving our Dart.

Morale of this story is – when you are modifying your car, keep the weight in mind!

Or, to quote the founder of Lotus automobiles, the lightweight, fun roadsters –

“Simplify, then add lightness”!



Have a 2013-2016 Dodge Dart with NO tip rear bumper but want the dual tips?

Ok, so you have a 2013-2016 Dodge Dart with the rear bumper without built in tips, and you want the dual tips.

No problem, this is an easy fix.

You can either:

A) Get the factory rear lower valance from us, and then find your own OEM tips, or have a local muffler shop weld on tips. (Click on the photo to jump to our product page)

We then recommend searching on Ebay for the OEM tips. Now these tips are about $130 (as of 4/21/17) each from a local dealership so you can try to get these cheaper on Ebay. Type into the search bar : Dodge Dart OEM Exhaust tips.

Or, if you want, you could do the same as above, but use the Mopar rear diffuser accessory. This piece is more expensive, but looks pretty cool. (Click on the photo to jump to our product page)

Option B, is where you get either the rear valance, or the Mopar rear diffuser from us, and then use the Flowmaster exhaust with tips. The photo below was of a Dodge Dart 2.4 Automatic with rear bumper without tips, and we installed the Mopar OEM rear valance, and then installed the Flowmaster exhaust with tips. We did not use the OEM tips on this car below. (Click on the photo to jump to the Flowmaster exhaust page)


Are your car windows opening and closing slow? Making squeaking or squealing noises?

One area of car maintenance that is seriously overlooked, is lubricating window moldings/rubber seals.
Over time, the more sun exposure your rubber moldings get, the more dry they get, and that causes windows to stick, windows to make odd squeaking or squealing noises, and other seal issues.

One product that is designed specifically for rubber moldings is Shin Etsu grease. This stuff is commonly known in the Honda world, however, it works on all rubber moldings no matter what kind of car you have. (Click the link below for more info and to buy)

This works on all rubber seals on the doors, windows, sunroofs, etc. Wherever you have rubber trim, you should apply this stuff. It will make the rubber moldings more flexible and pliable.

It can also help restore some of the black sheen of your moldings. It wont return them to like new black condition, but it helps regardless.

Moldings on bottom are old and dry, the moldings on top have Shin Etsu grease applied.
